[FIXED] Change the width of merged bins in Matplotlib and Seaborn

Issue

I have a table of grades and I want all of the bins to be of the same width

i want the bins to be in the range of [0,56,60,65,70,80,85,90,95,100] when the first bin is from 0-56 then 56-60 ... with the same width

sns.set_style('darkgrid') 
newBins = [0,56,60,65,70,80,85,90,95,100]

sns.displot(data= scores  , bins=newBins)

plt.xlabel('grade')
plt.xlim(0,100)
plt.xticks(newBins);

Expected output

how I can balance the width of the bins?

Solution

You need to cheat a bit. Define you own bins and name the bins with a linear range. Here is an example:

s = pd.Series(np.random.randint(100, size=100000))
bins = [-0.1, 50, 75, 95, 101]
s2 = pd.cut(s, bins=bins, labels=range(len(bins)-1))
ax = s2.astype(int).plot.hist(bins=len(bins)-
1)
ax.set_xticks(np.linspace(0, len(bins)-2, len(bins)))
ax.set_xticklabels(bins)

Output:

Old answer:

Why don't you let seaborn pick the bins for you:

sns.displot(data=scores, bins='auto')

Or set the number of bins that you want:

sns.displot(data=scores, bins=10)

They will be evenly distributed
